Sahih Bukhari Volume 2, Book 25, Hadith 1684

حَدَّثَنَا عَبْدُ اللَّهِ بْنُ رَجَاءٍ، حَدَّثَنَا إِسْرَائِيلُ، عَنْ أَبِي إِسْحَاقَ، عَنْ عَبْدِ الرَّحْمَنِ بْنِ يَزِيدَ، قَالَ خَرَجْنَا مَعَ عَبْدِ اللَّهِ ـ رضى الله عنه ـ إِلَى مَكَّةَ، ثُمَّ قَدِمْنَا جَمْعًا، فَصَلَّى الصَّلاَتَيْنِ، كُلَّ صَلاَةٍ وَحْدَهَا بِأَذَانٍ وَإِقَامَةٍ، وَالْعَشَاءُ بَيْنَهُمَا، ثُمَّ صَلَّى الْفَجْرَ حِينَ طَلَعَ الْفَجْرُ، قَائِلٌ يَقُولُ طَلَعَ الْفَجْرُ‏.‏ وَقَائِلٌ يَقُولُ لَمْ يَطْلُعِ الْفَجْرُ‏.‏ ثُمَّ قَالَ إِنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ ‏"‏ إِنَّ هَاتَيْنِ الصَّلاَتَيْنِ حُوِّلَتَا عَنْ وَقْتِهِمَا فِي هَذَا الْمَكَانِ الْمَغْرِبَ وَالْعِشَاءَ، فَلاَ يَقْدَمُ النَّاسُ جَمْعًا حَتَّى يُعْتِمُوا، وَصَلاَةَ الْفَجْرِ هَذِهِ السَّاعَةَ ‏"‏‏.‏ ثُمَّ وَقَفَ حَتَّى أَسْفَرَ، ثُمَّ قَالَ لَوْ أَنَّ أَمِيرَ الْمُؤْمِنِينَ أَفَاضَ الآنَ أَصَابَ السُّنَّةَ‏.‏ فَمَا أَدْرِي أَقَوْلُهُ كَانَ أَسْرَعَ أَمْ دَفْعُ عُثْمَانَ ـ رضى الله عنه ـ فَلَمْ يَزَلْ يُلَبِّي حَتَّى رَمَى جَمْرَةَ الْعَقَبَةِ يَوْمَ النَّحْرِ‏

Narrated By 'Abdur-Rahman bin Yazid : I went out with 'Abdullah, to Mecca and when we proceeded to am' he offered the two prayers (the Maghrib and the 'Isha) together, making the Adhan and Iqama separately for each prayer. He took his supper in between the two prayers. He offered the Fajr prayer as soon as the day dawned. Some people said, "The day had dawned (at the time of the prayer)," and others said, "The day had not dawned." 'Abdullah then said, "Allah's Apostle said, 'These two prayers have been shifted from their stated times at this place only (at Al-Muzdalifa); first: The Maghrib and the 'Isha. So the people should not arrive at Al-Muzdalifa till the time of the 'Isha prayer has become due. The second prayer is the morning prayer which is offered at this hour.' " Then 'Abdullah stayed there till it became a bit brighter. He then said, "If the chief of the believers hastened onwards to Mina just now, then he had indeed followed the Sunna." I do not know which proceeded the other, his ('Abdullah's) statement or the departure of 'Uthman. Abdullah was reciting Talbiya till he threw pebbles at the Jamrat-al-'Aqaba on the Day of Nahr (slaughtering) (that is the 10th of Dhul-Hijja).
